showing the sash-closing and releasing cam,

Fig 11 is a detail vertical section in the plane of the cam-bolt, and Fig. 12 is an elevation of the cam strike-plate on the swingin sash.

y invention is intended for use on casement windows hinged at the side and swinging outwardly. In dwellings where such easements are employed the screens 13 are disposed on the inside of the windowkfraines, and the window-sash 14 is preferably made with rabbets i'itting into corresponding parts of the frame 15, as shown in Fig. 1. In the frame member 16 agaiilst which the free or swinging side of the sash closes, there is made an opening which extends from the edge of the sash to the inner side or edge of the frame member. The outer end of said opening is preferably lined with a metallic bushing or lining sleeve 17, as shown in Fig. 8. A chain 18 is passed through said opening and its outer end is connected with a plate 19 secured to the Vsash 14, a short coil spring 20 being preferably interposed adjoining the plate, for the purpose hereinafter described. On the inner side or edge of the frame member 16 there is anpescutchecnV 21 having a circular `opening through 1922. sei-'iai No. 558,242.

which the chain may pass freely, and at one side of the -opening a slot into which a link of the chain may be passed edgewise, as indicated in Fig. 9, so as to fasten and prevent movement of the chain longitudinallyV through the opening. In the upper part of the escutcheon 21 is an opening for the cambolt' 22, which has at its inner end a handle 23 by which it may be turned. Said cambolt extends horizontally through the frame member 16, and its outer end portion passes through the sides of the cam-casing 24 which is inortised into the frame adjoining the edge of the s ash 14.- On the bolt within said casing 24 is secured the cam 25, which is shaped somewhat like a screw-propeller, having symmetrical oppositely beveled or inclined end-portions which lie wholly within the casing 24 when the cam is in a vertical position as shown in Fig. 10, and which project laterally through the open side of the casing when the cam is turned to a horizontal position. On the sash, at the edge thereof adjoining the cam-casing, there is secured a strike-plate 26, having therein a rectangular opening across which is extended a diagonal bar 27, said bar dividing the opening into two triangular parts, as shown in Fig. 12. Said bar 27 is adapted to be engaged by the beveled end portions of the cani, the upper or inner edge of the bar being engaged when the cam is turned in one direction, and the lower or outer edge of the bar being engaged when the Vcam is turned in the other direction. Thus, by turning the cam-handle 23 in one direction the sash may be pulled inwardly toward the casing and the window held securely in closed position, and by turning the handle in the other direction the sash may be pushed outwardly to loosen the same from the window frame in the event that, from absorption of Yinoisture or other causes, the sash should swell so as `to stick in the casing and not start freely to swing outwardly from the frame.

The sash is swingably hung on hinges each having a plate 28 fitting upon and secured to the frame 15, and a plate 29 secured to the sash and preferably L-shaped so as to fit upon a corner of the sash as shown in Fig. 2. The plate 28 has lugs 30 and 31 thereon, and between said lugsthe lugs 32 and 33 of the plate 29 extend as shown in Fig. 4. A pintle is provided having a stem 34, an enlarged neck-portion 35 extending through the lugs 30 and 32, a

head portion 36 above the lug 30, and a sleeve 37 screwed onto the lower end of the stem 34 and extending through the lugs 31 and 83. round the stem 34 is disposed a coil spring 38 of which one end is connected with the pintle and the other engages the plate 29 so that unwinding ot the spring will tend to swing the plate 29 and the sash outwardly. The spring is enclosed by a loose cylindrical sleeve 39 ot' which the ends t upon the neck-portion and the sleeve 37 oit the pintle. The spring is placed under tension by turning the pintle, there being holes in the head 36 lor the insertion of aV pin by which it may be turned, and on the under side ot the head there being ratchetteeth which engage similar teeth, formed on the upper side ot the lug 30, to prevent rotation of the pintle relative to said lug and the plate 28.

On the back side of the plate 28, extending into a recess made in the frame l5, is a casing 40 which may be integral with the plate andot the form shown in Figs. 3, 5, 6 and 7. @n the plate 29 is a curved tongue 4l which normally extends into the casing 40. The outer curved side of the tongue 41 has ratchet-teeth formed thereon as shown. A pawl 42 adapted to engage said ratchetteeth is pivoted within the casing, the end ot the pawl being normally pressed toward the teeth by a spring 43 engaging the tailportion of the pawl. rt the end ot the tongue is a hook 44 adapted to engage a lug 45 on the pawl when the plate 29 is swung outwardly as shown in Fig. 6, and to turn the pawl to a position at which it will not engage the ratchet-teeth. When the pawl is turned momentarily to this position, a flat spring 46, arranged in the casing as shown in Figs. 6 and '7, is permitted to rise up in front of the pawl to hold it in the disengaged position. YWhen the plate 29 is swung inwardly to the position shown in Fig. 3, a wedge-shaped .portion 47 on t-he lower side of the tongue 41, indicated in Fig. 5, pushes the spring 46 down so that it is disengaged from the pawl and the latter thus permitted to again engage the ratchet-teeth on the tongue.

By the foregoing means the movement of the swinging sash may be controlled an'd the same secured at any desired position, either fully closed or open to any extent, without opening the screen 13. rlhe sash is drawn to the closed position by pulling upon the chain 18 inwardly through the escutcheon 21, and at the end of the movement the spring 20, by elongating more or less, always enables one oi' the links to be dropped into the notch at the bottom ot the opening through the escutcheon, as described. lllhe sash may be further secured in the closed position by turning the cam 25 to engage and press inwardly upon the bar 27 oit' the strike-plate 26. When it is desired to open the window, should the sash stick in the trame it may be released and started to swing outwardly by turning the cam 25 to push outwardly upon the diagonal bar 2.7 ot the strike-plate, the chain 18 being released trom the notch in the escutcheon and held so as to control the outward swinging movement which is caused by springs 38 ot the hinges. After the sash has swung out tar enough to permit the pawls 42 to engage any of the teeth on the tongues 41, said pawls then prevent the return or" the sash to closed position, and, by placing the chain in tension and engaging one of its links in the notch of the escutcheon, the sash is securely held in the position to which it has swung, and cannot be moved in either direction by wind pressure or the like. lli/hen it is desired to close the sash it is rst permitted to swing to the full outward or open position, so that the hinge parts are in the positions shown in Fig. 6, and the pawls are thereby disengaged from the ratchet-teeth and are retained in the disengaged positions by the springs 46 until the sash is swung to the full inward or closed position. it this position the springs 46 are disengaged -from the pawls by the wedge-portions 47, as before described, so that the pawls may again act when the sash is allowed to swing outwardly.

Now, having described my invention, what I claim and desire to Secure by Letters Patent is:

1. In a device ot the class described, a hinge having two pintle-connected plates, a ratchet-toothed member carried by'one of said plates, a pawl connected with the other plate, means constantly tending to move the pawl to a position tor engaging said ratchettoothed member, a lug on said ratchettoothed member adapted to engage the pawl when the plate is moved to an extreme position and turn the pawl to a position at which it *cannot engage the ratchet-teeth` a spring :tor retaining the pawl in the 'latter position, and a wedge-portion on the ratchet-toothed member adapted to engage said spring and release it from the pawl when the plate is moved to the other extreme position.

2. In a mechanism of the class described, the combination with a hinged element, spring means tending to move the same outwardly, and a flexible tension member for positively limiting outward movement ot the element trom intermediate adjusted positions, of a ratchet-toothed,member connected with said element, a pawl engageable with said member to positively limit inward movement ot the element from intermediate positions, and means on said member for disengaging the pawl from the ratchettoothed portion thereof when the element is swung outwardly to an extreme position.

3. ln a mechanism of the class described,

the combination With a swinging element, spring means tending to move the same outwardly, and a flexible tension member for positively limiting outward movement of the element from intermediate adjusted positions, of a ratchet-toothed member Connected with said element, a paWl engageable with said member to positively limit inward movement of the element from intermediate 10 positions, means on said member for disengaging the paWl from the ratchet-toothed portion thereof when the swinging element is moved outwardly to an eXtreme position, retaining means for holding the paWl at disengaged position, and means on said member for moving the retaining means to release the paWl therefrom When the swinging element ismoved inwardly to an eX- treme position.
